Illinois remains a reliably Democratic state, with the open Senate seat following Dick Durbin's retirement expected to stay in Democratic hands. Juliana Stratton secured the nomination after prevailing in a competitive primary against Raja Krishnamoorthi and Robin Kelly, while Don Tracy emerged as the Republican nominee. The latest public poll from early October showed Stratton ahead by 13 points, and forecasts project a Democratic margin in the high teens. Trader pricing on margin buckets clusters most heavily around 15-25 points, reflecting the state's partisan lean and limited recent campaign developments that could widen or narrow the spread. A Republican upset remains a low-probability outcome priced below 3 percent.
